Define the term: Arteries.
Blood vessels that carry blood away from the heart to various parts of the body. Most arteries carry oxygenated blood, except the pulmonary artery.
Blood vessels that carry blood towards the heart from various parts of the body.
Tiny blood vessels where exchange of substances between blood and tissues occurs.
Blood vessels that only carry deoxygenated blood throughout the body.
Define the term: Respiratory System.
The body system responsible for gas exchange, allowing oxygen to enter the blood and carbon dioxide to be removed. It includes the nose, trachea, lungs, and diaphragm.
The body system responsible for breaking down food and absorbing nutrients. It includes the stomach and intestines.
The body system responsible for transporting blood throughout the body. It includes the heart and blood vessels.
The body system responsible for movement and support. It includes muscles and bones.
Define the term: Sulci.
Grooves or depressions on the surface of the heart that mark the boundaries between the chambers of the heart and contain blood vessels.
Valves that regulate blood flow between the chambers of the heart.
Muscular walls that separate the left and right sides of the heart.
Small arteries that supply blood directly to the heart muscle.
Define the term: Vein.
Blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood, except the pulmonary vein.
Blood vessels that carry blood away from the heart.
A type of nerve cell found in the brain.
A chamber of the heart that pumps blood to the body.
Define the term: Oxygenated Blood.
Blood that is rich in oxygen and low in carbon dioxide, usually found in the left side of the heart and arteries (except pulmonary artery).
Blood that is rich in carbon dioxide and low in oxygen, usually found in veins and the right side of the heart.
Blood that contains no gases and is found only in the lungs.
Blood that is only present in the digestive system and carries nutrients.
Define the term: Deoxygenated Blood.
Blood that is low in oxygen and high in carbon dioxide, usually found in the right side of the heart and veins (except pulmonary vein).
Blood that is rich in oxygen and low in carbon dioxide, usually found in arteries.
Blood that is only found in the left side of the heart.
Blood that contains no carbon dioxide at all.
Define the term: Bicuspid Valve.
Also called the mitral valve, it is found between the left atrium and left ventricle, preventing backflow of blood into the atrium.
Also called the tricuspid valve, it is found between the right atrium and right ventricle.
It is a valve found between the left ventricle and the aorta.
It is a valve that prevents blood from flowing from the ventricles to the atria during contraction.
Define the term: Tricuspid Valve.
A valve located between the right atrium and right ventricle, it prevents the backflow of blood into the right atrium.
A valve located between the left atrium and left ventricle, it prevents the backflow of blood into the left atrium.
A valve located between the right ventricle and pulmonary artery, it prevents the backflow of blood into the right ventricle.
A valve located between the left ventricle and aorta, it prevents the backflow of blood into the left ventricle.
Define the term: Pulmonary Circulation.
The path through which deoxygenated blood is pumped from the heart to the lungs to receive oxygen, then returned to the heart.
The process by which oxygenated blood is distributed from the heart to the rest of the body.
The movement of blood between the heart and the kidneys for filtration.
The circulation of blood within the heart chambers only.
Define the term: Systemic Circulation.
The pathway in which oxygenated blood is pumped from the heart to the entire body, and deoxygenated blood is returned back to the heart.
The pathway in which deoxygenated blood is pumped from the heart to the lungs and oxygenated blood is returned to the heart.
The process by which nutrients are absorbed from the digestive tract into the bloodstream.
The movement of blood only within the heart chambers.
Which of the following diagrams correctly represents a labelled mammal's heart?
A diagram showing four chambers: left atrium, right atrium, left ventricle, right ventricle, with major vessels labelled.
A diagram showing three chambers: left atrium, right atrium, and a single ventricle.
A diagram showing two chambers: one atrium and one ventricle.
A diagram showing four chambers but without any labels.
The pulmonary pathway refers to the route taken by blood from the heart to the lungs and back. Which of the following best describes this pathway?
Blood flows from the right ventricle to the lungs via the pulmonary artery, gets oxygenated, and returns to the left atrium via the pulmonary veins.
Blood flows from the left ventricle to the lungs via the aorta, gets oxygenated, and returns to the right atrium via the pulmonary veins.
Blood flows from the right atrium to the lungs via the pulmonary vein, gets oxygenated, and returns to the left ventricle via the pulmonary artery.
Blood flows from the left atrium to the lungs via the pulmonary artery, gets oxygenated, and returns to the right ventricle via the pulmonary vein.
The systemic pathway is best described as:
The circulation of blood from the heart to the body (except lungs) and back to the heart.
The circulation of blood between the heart and the lungs.
The process of oxygen exchange in the alveoli.
The movement of nutrients from the digestive tract to the bloodstream.
