Blood
This component of blood comes in three types, which each serve different functions.
What are blood cells?
What is the cornea?
This hollow muscular organ is divided into two parts (left and right) which are completely separate
What is the heart?
This artery originates from the right ventricle
What is the pulmonary artery?
The smaller, upper chamber of the heart
What is the atrium?
This component of blood is made up of water with minerals, nutrients, waste products, proteins, and dissolved hormones
What is blood plasma?
These make up the closed circuit that a vertebrate’s blood circulates through
What are blood vessels?
This organ often appears in valentines imagery
What is the heart?
This artery originates from the left ventricle
What is the aorta artery?
The larger, lower chamber of the heart
What is the ventricle?
These (commonly referred to as red blood cells) contain hemoglobin, are disk-shaped without a nucleus, and are the most numerous
What are erythrocytes?
These carry blood from the heart to other organs. They have thick muscular walls and are elastic.
What are arteries?
The heart is formed by this thick wall of muscle tissue
What is the myocardium?
These four veins arrive at the left atrium
What are the pulmonary veins?
This valve allows blood to pass from the atrium to the ventricle, but not the other way around
What is the atrioventrivular valve?
These (commonly referred to as white blood cells) have a nucleus and can be classified into three different types
What are leukocytes?
These carry blood to the heart from other tissues. They have thinner walls and valves that keep blood from traveling backwards.
What are veins?
This double membrane covers the interior and exterior of the heart wall
What is the pericardium?
These two veins arrive at the right atrium
What are the venae cavae?
This valve is located between the right atrium and right ventricle
What is the tricuspid valve?
These fragments of cells allow blood to coagulate
What are Thrombocytes or platelets?
These microscopic blood vessel’s walls are formed by only one layer of cells to allow for exchange
What are capillaries?
This is the thin wall of cells that make up part of the pericardium
What is the endocardium?
At the start of the pulmonary and aorta arteries these valves prevent blood from reentering the heart once it has been pumped out.
What are sigmoid valves?
This valve is located between the left atrium and the left ventricle
What is the bicuspid or mitral valve?
