Blood Tracing Frames 1-677 Flashcards
From the right atrium the blood passed 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 the 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 scroll, it picks up _______ and at the same time gives off _________
Oxygen, carbon dioxide
The blood flows through the capillaries, around the alveoli, and then enters the
Pulmonary veins
The pulmonary veins then carry blood away from the
Lungs
The pulmonary _________ carries the blood to the lungs
Artery
The pulmonary _______ carry blood from the lungs
Veins
The pulmonary veins carry the blood to the ____ ________ of the heart
Left atrium
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 it 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 the _____ ______ from which it enters the right atrium to begin the cycle again.
Vena cava
The aorta arises from the left ventricle and arches backward, descending to the left. Subdivisions are
Ascending aorta
Arch of the aorta
Thoracic aorta
Abdominal aorta
The ascending aorta has two small branches, the right and left _______ ________ which supply blood to the heart
Coronary arteries
The coronary arteries divide into many tiny branches called
Capillaries
From the capillaries the hearts blood supply flows into the
Cardiac veins
From the cardiac veins the heart’s blood supply flows into the
Coronary sinus
From the coronary sinus the blood enters the
Right atrium
The arch of the aorta contains three branches. The first and largest branch is called the
Innominate artery a.k.a. Brachiocephalic 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
The Innominate or brachiocephalic artery divides into two branches. The branch going upwards is called the
Right common carotid artery
The other branch of the Innominate or brachiocephalic artery extends towards the right arm. It is called the
Right subclavian artery
Branching off both the right and left subclavian arteries and extending upward towards the head are the
Vertebral arteries
The 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 artery passes the first rib it is called the axillary artery. After the axillary artery passes the axilla (armpit) it is called the
Brachial artery
Just below the brachial artery divides into two branches, the
Radial artery and the ulnar artery
Both the radial and the ulnar arteries extend into the palm of the hand where the subdivide into the
Superficial and deep volar a.k.a. palmer arches
The superficial and deep volar a.k.a. palmer arches extend into the
Digital arteries
