Describe the systemic circuit. (Module 19.1B) Describe the systemic circuit. (Module 19.1B) The systemic circuit transports blood from the right ventricle through the pulmonary arteries, capillaries in the lungs, and pulmonary veins and returns it to the left atrium. The systemic circuit transports blood through the arteries, capillaries, and veins of the body from the left ventricle to the right atrium. The systemic circuit consists of the vasculature in the heart. The systemic circuit transports blood from the left ventricle through the pulmonary arteries, capillaries in the lungs, and pulmonary veins and returns it to the right atrium. The systemic circuit transports blood from the left ventricle through the pulmonary veins, capillaries in the lungs, and pulmonary arteries and returns it to the right atrium.

Systemic circuit is defined as one of the two circuit of circulation that occurs in human body.

The circulatory system is divided into two phases in the human body. They are:

A. Pulmonary circulation

B. Systemic circulation.

The pulmonary circulation is the short circuit of circulation that starts from the right ventricle, goes to lungs via pulmonary artery and returns to left auricle via pulmonary vein.

The systemic circulation is the bigger circuit that starts from the left ventricle, goes to each and every organ of the body via aorta, and returns to the right auricle via venacava.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
