Cardio Overview
This cardiovascular component pumps blood throughout the body.
What is the heart?
These blood cells carry oxygen using hemoglobin.
What are red blood cells (erythrocytes)?
This is the process that stops bleeding after a blood vessel is damaged.
What is hemostasis?
What are arteries and veins?
The left side of the heart pumps this type of blood.
What is oxygenated blood?
These tube-like structures carry blood throughout the body.
What are blood vessels (arteries and veins)?
This liquid part of blood carries water, nutrients, hormones, proteins, and wastes.
What is plasma?
All blood types can receive this type of blood, which lacks all possible antigens.
What is O negative (O-)?
These blood vessels carry blood back toward the heart.
What are veins?
This test records the electrical activity of the heart and can help detect heart problems.
What is an EKG?
This cardiovascular component transports oxygen, nutrients, wastes, hormones, and immune cells.
What is blood?
These cell fragments help with blood clotting.
What are platelets (thrombocytes)?
This third step of hemostasis forms fibrin threads that strengthen the clot.
What is coagulation (blood clotting)?
These blood vessels carry deoxygenated blood from the heart to the lungs.
What are the pulmonary arteries?
This is the most muscular chamber of the heart and helps to pump blood from the heart to the rest of the body.
What is the left ventricle?
The cardiovascular system is essential because cells need oxygen and nutrients and must remove this gaseous waste product.
These leukocytes include T cells and B cells.
What are lymphocytes?
These immune proteins can attack blood cells with unfamiliar antigens.
What are antibodies?
This is the largest artery in your body! It carries oxygenated blood from the left ventricle to the rest of the body.
What is the aorta?
This is the first structure in the heart’s conduction system and is often called the natural pacemaker.
What is the sinoatrial (SA) node?
The cardiovascular system works with many other body systems to keep you alive. Name one of those systems and briefly explain your answer.
Many possible answers! Ex. the respiratory system: lungs add essential oxygen + remove toxic carbon dioxide from blood
This leukocyte uses enzymes to digest parasitic worms.
What are eosinophils?
During the second step of hemostasis, this protein helps bind platelets to exposed collagen fibers in order to form a platelet plug.
What is von Willebrand factor?
What is missing?
Superior/Inferior Venae Cavae → Right Atrium → __________ → Right Ventricle → Pulmonary Valve → Pulmonary Arteries → Lungs
This term is used to describe a heartbeat that is abnormally fast, exceeding 100 beats per minute at rest.
What is tachycardia?
