Week 8 Lab Quiz Flashcards
What is A and its function?
Superior vena cava - The superior vena cava carries deoxygenated blood from the upper half of the body back to the heart.
What is B and its function?
Right atrium - receives deoxygenated blood through three major veins
What is C and its function?
Tricuspid valve - prevents back-flow and Allows deoxygenated blood to go from right atrium to right ventricle
What is D and its function?
Right ventricle - receives deoxygenated blood from right atrium
Side note - It then pumps this blood through the pulmonary valve into the pulmonary trunk, which splits into the right and left pulmonary arteries.
What is E and its function?
Interventricular septum - prevents the mixing of oxygenated and deoxygenated blood
What is F and its function?
Aorta - carries oxygenated blood from the left ventricle to the entire body through its branches.
What is G and its function?
Left pulmonary artery - carries deoxygenated blood from the right ventricle to the left lung.
What is H and its function?
Pulmonary valve - prevents backflow of blood from the pulmonary trunk into the right ventricle.
Side note - During ventricular systole (contraction), the valve opens, allowing deoxygenated blood to flow from the right ventricle into the pulmonary arteries and on to the lungs.
• During ventricular diastole (relaxation), the valve closes, ensuring that blood does not flow back into the right ventricle.
What is I and its function?
Left pulmonary veins - transport oxygenated blood from the left lung back to the left atrium of the heart.
What is J and its function?
Aortic semilunar valve - The aortic valve allows oxygenated blood to flow from the left ventricle into the aorta during ventricular systole (contraction).
What is K and its function?
Bicuspid valve - The bicuspid valve allows oxygenated blood to flow from the left atrium to the left ventricle.
Also -
It prevents backflow of blood into the left atrium when the left ventricle contracts (during systole).
What is L and its function?
Left ventricle - The left ventricle receives oxygenated blood from the left atrium via the mitral valve.
Also -
It pumps this blood into the aorta through the aortic semilunar valve to supply oxygen and nutrients to the entire body via systemic circulation.
What is A and its function?
Right common carotid - The right common carotid artery carries oxygenated blood from the heart to the head and neck.
What is B and its function?
Subclavian vein - The subclavian vein returns deoxygenated blood from the following areas back to the heart:
1. Upper limbs – via the axillary vein.
2. Head and neck – indirectly, through its junction with the internal jugular vein.
What is C and its function?
Axillary vein - The axillary vein drains deoxygenated blood from the upper limb, shoulder, and parts of the chest wall
What is D and its function?
Brachial arteries - The brachial artery is the primary artery of the upper arm, delivering oxygenated blood to the muscles and tissues of the arm, forearm, and hand.
What is E and its function?
Radial arteries - The radial artery supplies oxygenated blood to:
• Lateral forearm muscles.
• Wrist and hand (via superficial and deep palmar arches).
• Thumb and parts of the index finger.
What is f and its function?
Ulnar arteries -
The ulnar artery supplies oxygenated blood to:
• The medial forearm (muscles and soft tissues).
• The hand, including the fingers, through the superficial and deep palmar arches
What is G and its function?
Palmar arch - The palmar arches supply oxygenated blood to:
• The palm of the hand.
• The fingers through their branches, called palmar digital arteries.
What is H and its function?
Digital arteries - The digital arteries deliver oxygenated blood to the tissues of the fingers and toes, including:
