All are functions of a heart excepts;
Generate blood pressure
Produce plasma protein
Routing blood
Regulate blood supply
Which of the following is not a characteristic of capillaries?
Smallest of the 3 blood vessels
Huge network of them which links veins and arteries
Thick, elastic walls
Diastolic pressure is...
The higher blood pressure measurement
The pressure when the heart rests between beats
The pressure when the heart pushes blood through arteries
The lower blood pressure measurement
Which chamber of the heart receives oxygenated blood from the lungs via the pulmonary vein?
Left Atrium
Right Atrium
Left Ventricle
Right Ventricle
Which blood vessels have thick, muscular and elastic walls to withstand the high pressure?
Veins
Arteries
Capillaries
Alveoli
Which blood vessels have valves to prevent backflow of blood?
Capillaries
Alveoli
Arteries
Veins
What is the correct path through the circulatory system which describes the passage of a blood clot originating in the left leg?
Vena cava → left atrium → left ventricle → lungs → right atrium → right ventricle → aorta
Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta
Vena cava → left atrium → right atrium → lungs → left ventricle → right ventricle → aorta
Vena cava → right atrium → left atrium → lungs → right ventricle → left ventricle → aorta
A tiny blood vessel that allows for exchange between the blood and cells in the tissues in the body is called a
Blood vessel
Vein
Capillary
Artery
What do red blood cells do?
Carry oxygen from the lungs to the body cells and transport carbon dioxide from the cells back to the lungs
Collects blood from the capillaries and drain it into the veins
Keeps blood flowing in one direction to the heart and prevent blood from flowing backwards
Bring nutrients to the cells and carries away waste materials
The left ventricle has a larger muscle, why?
Because the blood is thicker when oxygenated
This side pushes blood around the whole body which needs more power
The aorta puts up a lot of resistance
Genetic abnormality
