Solution
The circulatory system is composed of the heart, blood, and blood vessels.
Hemoglobin is the oxygen-carrying molecule of a red blood cell.
A normal blood pressure should be about 120/80.
Specialized proteins that aid in destroying infectious agents are antibodies.
The large vein that carries deoxygenated blood into the heart from the lower body is the inferior vena cava.
The body system responsible for carrying blood from the heart to the lungs and back to the heart again is the pulmonary circulatory system.
Systemic circulation carries blood between the heart and body.
In a closed circulatory system, a heart pumps blood through a system of blood vessels. The blood remains in the vessels and does not come in direct contact with the body's tissues. This is true.
The heart beats about 2.5 billion times in the average human lifetime.
The pulmonary artery carries deoxygenated blood from the heart to the lungs. So, the statement is false.
A vaccine is a weakened or inactive version of a pathogen that stimulates the body's production of
