VOCABULARY 2
ANATOMY OF THE HEART
CIRCULATION
MASTERING BIOLOGY
300
A circulatory system in which fluid called hemolymph bathes the tissues and organs directly and there is no distinction between the circulating fluid and the interstitial fluid.
What is an open circulatory system?
300
In invertebrates with an open circulatory system, this is the blood fluid that bathes tissues.
What is hemolymph?
300
In animals, a vessel that carries blood toward the heart. In plants, a vascular bundle in a leaf.
What is a vein?
300
A circulatory system consisting of separate pulmonary and systemic circuits, in which blood passes through the heart after completing each circuit.
What is double circulation?
300
Organisms with a circulatory body fluid that is distinct from the fluid that directly surrounds the body's cells are likely to have this.
What is a closed circulatory system?
300
A muscular pump that uses metabolic energy to elevate the hydrostatic pressure of the circulatory fluid (blood or hemolymph). The fluid then flows down a pressure gradient through the body and eventually returns to this organ.
What is the heart?
300

A connective tissue with a fluid matrix called plasma in which red blood cells, white blood cells, and cell fragments called platelets are suspended.

DJ What is blood?

300
A vessel that carries blood away from the heart to organs throughout the body.
What is an artery?
300

A circulatory system consisting of a single pump and circuit, in which blood passes from the sites of gas exchange to the rest of the body before returning to the heart.

DJ What is single circulation?

300
The fluid that moves around in the circulatory system of a typical anthropodis.
What is the interstitial fluid?
400
A closed circulatory system with a heart and branching network of arteries, capillaries, and veins. It is a characteristic of vertebrates.
What is the cardiovascular system?
400
A circulatory system in which blood is confined to vessels and is kept separate from the interstitial fluid.
What is a closed circulatory system?
400
A vessel that conveys blood between an artery and a capillary bed.
What is an arteriole?
400
The branch of the circulatory system that supplies the lungs.
What is pulmonary circuit?
400

The best description of an artery.

Dj What is arteries carry blood away from the heart?

400
A network of capillaries in a tissue or organ.
What is a capillary bed?
400

A chamber of the vertebrate heart that receives blood from the veins and transfers blood to a ventricle.

DJ What is the atrium?

400
A microscopic blood vessel that penetrates the tissues and consists of a single layer of endothelial cells that allows exchange between the blood and interstitial fluid.
What is a capillary?
400

A branch of the circulatory system in many amphibians that supplies the lungs and skin.

T What is the pulmocutaneous circuit?

400
The materials present in arterioles that is not present in capillaries.
What is circular smooth muscle cells that can alter the size of the arterioles?
500
A chamber of the vertebrate heart that receives blood from the veins and transfers blood to a ventricle.
What is an atrium?
500
A heart chamber that pumps blood out of the heart. Also, a space in the vertebrate brain, filled with cerebrospinal fluid.
What is a ventricle?
500
A vessel that conveys blood between a capillary bed and a vein.
What is a venule?
500
The branch of the circulatory system that supplies oxygenated blood to and carries deoxygenated blood away from organs and tissues throughout the body.
What is the systemic circuit?
500
The set of blood vessels with the slowest velocity of blood flow.
What are the capillaries?
