Blood Tracing Flashcards
Blood entering the heart flows into the
Right Atrium
From the right atrium, the blood passes through a valve known as the
Tricuspid Valve
The blood flows through the tricuspid valve into the
Right Ventricle
From the right ventricle the blood passes through the
Semilunar Valves
After passing through the semilunar valves, the blood enters the
Pulmonary Artery
The pulmonary artery carries blood to the
Lungs
In the lungs the pulmonary artery subdivides into many tiny branches called
Capillaries
The capillaries in the lungs are in direct contact with many tiny air sacs called
Alveoli
As the blood flows around the alveoli, it picks up
Oxygen
As the blood flows around the alveoli, it gives off
Carbon Dioxide
The blood flows through the capillaries, around the alveoli, and then enters the
Pulmonary Veins
The pulmonary veins carry blood
Away from the lungs
The pulmonary __________ carry blood to the lungs
Artery
The pulmonary veins carry the blood to the
Left atrium of the heart
From the left atrium the blood passes through the
Bicuspid valve
From the lungs, the blood flows through the pulmonary veins to the left atrium, then flows through the bicuspid valve into the
Left Ventricle
From the left ventricle, the blood passes through another set of
Semilunar valves
From the semilunar valves, the blood flows into the main artery
The Aorta
From the aorta the blood goes to all parts of the body, eventually flowing into this
Vena Cava
From the vena cava, the blood enters this to begin the cycle again
Right Atrium
Describe the circulation of the blood through the heart, beginning with the right atrium
Right atrium, through the tricuspid valve to right ventricle, through semilunar valves to pulmonary artery to lungs to capillaries, around alveoli to pick up oxygen and give off carbon dioxide, to pulmonary veins to left atrium through bicuspid valve to left ventricle through semilunar valves to aorta to all parts of the body to vena cava and return to right atrium
The aorta arises from the left ventricle and arches backward, descending to the left. For descriptive purposes it may be considered as being subdivided into
Ascending aorta
Arch of the aorta
Thoracic Aorta
Abdominal Aorta
The ascending aorta has two small brances, which supply blood to the heart muscle
Right and left coronary arteries
The coronary arteries divide into many tiny branches called
Capillaries
From the capillaries the hearts blood supply flows into the
Cardiac Valves
From the cardiac veins, the heart’s blood supply flows into the
Coronary Sinus
From the coronary sinus the blood enters the
Right atrium
Trace the path of the blood as it flows to nourish the heart
From the heart to ascending aorta to right and left coronary arteries to heart capillaries to cardiac veins to coronary sinus to right atrium
The arch of the aorta contains three branches. The first and largest branch is called the
Innominate Artery
The second branch of the aortic arch is called the
Left Common carotid Artery
The third branch of the aortic arch is called the
Left Subclavian Artery
What are the three branches of the aortic arch, in order?
Innominate Artery, Left Common Carotid Artery, Left Subclavian Artery
The innominate artery divides into two branches. The branch going upward is called the
Right Common Carotid Artery
The second branch of the innominate artery extends toward the right arm, called the
Right Subclavian
Branching off both the right and left subclavian arteries and extending upward towards the head are the
Vertebral Arteries
The right vertebral artery comes from the
Right Subclavian Artery
The left vertebral artery comes from the
Left Subclavian Artery
The left subclavian arteries supply blood to the
Upper Extremities
At the outer border of the first rib the subclavian artery becomes the
Axillary Artery
After the subclavian passes the first rib, it is called the
Aaxillary Artery
After the axillary passes the axilla, it is called the
Brachial Artery
Just below the elbow, the brachial artery divides into two branches, called the
Radial and ulnar arteries
Both the radial and the ulnar arteries extend into the palm of the hand where they subdivide into the
Superficial and Deep Volar Arches
The superficial and deep volar arches extend into the
Digital Arteries
From the digital arteries the blood flows into
Arterioles and Capillaries
Trace the path of the blood from the heart to the capillaries of the left hand
Heart to ascending aorta to arch of the aorta to left subclavian artery to axillary artery to brachial artery to radial and ulnar arteries to superficial and deep volar arches to digital arteries to arterioles to capillaries
From the capillaries, the blood flows into the
Venules
The venules then carry the blood to the
Superficial and deep volar venous arches
The blood from the superficial volar venous arches flows into a network of superficial veins, known as the
Dorsal Venous Network of the hand
From the dorsal venous network, two large veins extend superficially upward, returning the blood towards the heart, known as the
Cephalic and Basilic Veins
This extends superficially from the dorsal venous network along the thumb side of the arm
Cephalic Vein
This extends superficially upward along the little finger side of the arm
Basilic Vein
The cephalic vein extends upward to empty into the
Axillary Vein
The basilic vein extends superficially upward and then joins the brachial vein to form the
Axillary Vein
The blood from the venules enters the
Superficial and deep volar venous arches
The superficial volar venous arches branch into the
Cephalic vein and Basilic Vein
The deep volar venous arches branch into the
Radial and Ulnar Veins
The radial and ulnar veins combine just below the elbow to form the
Brachial Vein
The Brachial vein extends upwards into the
Axillary Vein
The axillary vein also receives the blood flowing from the
Cephalic vein and Basilic vein (once joined with the brachial vein)
On the right side the axillary vein extends into the
Right Subclavian Vein
The left subclavian vein empties into the
Left Innominate Vein
The right and left innominate veins empty into the
Superior Vena Cava
The superior vena cava extends into the
Right Atrium of the Heart
Trace the path of the blood from the heart to the left hand and return
Left ventricle of heart, ascending aorta, left subclavian artery from arch of aorta, axillary artery, brachial artery, radial and ulnar arteries, superficial and deep volar arches, digital arteries, arterioles, capillaries, venules, superficial and deep volar arches, from superficial to dorsal venous network, to cephalic vein to axillary vein and from basilic vein to brachial vein to axillary vein, from depp volar to radial and ulnar veins, to brachial vein, to axillary vein, left subclavian vein, left innominate vein, superior vena cava, Right Atrium of the heart
From the first artery in the arch of the aorta is the
Innominate artery
The second artery in the arch of the aorta is the
Left Common Carotid
The third artery in the arch of the aorta is the
Left Subclavian
The innominate artery subdivides into the
Right Common Carotid and Right Subclavian
Each of the subclavian artery has an upward branch, called the
Vertebral Artery
These arteries extend upward and supply blood to the head and neck
Common Carotids and Vertebral
The common carotid arteries extend upward along the traches until they reach the upper border of the
Thyroid cartilage
At the upper border of the thyroid cartilage, the common carotids divide into the
External carotid and Internal Carotid Arteries
The external carotid arteries supply blood to the
Neck, face, mouth, jaws, and scalp
The internal carotid arteries supply blood to the
Brain, eyes, forehead, and nose
The first principal branch of the external carotid artery is the
Superior Thyroid Artery
The Superior Thyroid Artery supplies blood to the
Thyroid Gland
The second principal branch of the external carotid artery is the
Lingual Artery
The lingual artery leads to the
Tongue
The third branch off the external carotid artery is the
External Maxillary Artery
The external Maxillary Artery leads toward the
Face
The fourth principal branch of the External Carotid Artery is the
Occipital Artery
The occipital artery leads toward the
Scalp
After the occipital branch, the external carotid artery subdivides into two main branches
Superficial temporal and Internal Maxillary Arteries
The internal maxillary artery leads towards the
Deep structures of the face, towards the covering of the brain, and towards the teeth and jaws
The blood flows through all of these arteries into arterioles, into capillaries, into venules, and then finally two large veins, the
Posterior facial and posterior Auricular Vein
The posterior facial vein and the posterior auricular vein combine to form the
External jugular vein
The external jugular veins empty into the
Subclavian veins
The right external jugular vein empties into the
Right Subclavian Veins
