Biology 101: Circulatory, Respiratory, and Lymphatic Systems Study Guide and Review

In this quick and easy biology final exam study guide, we share our notes and review the circulatory, respiratory, and lymphatic systems in the following 3 sections. From the anatomy of the heart and blood flow in the circulatory system to the breaths we take traveling through the lung and lymphatic flow.

Circulatory System: Heart Structures and Functions

Circulatory System: Heart Structures and Functions; Blood flows through the heart in the following order: body –>inferior/superior vena cava –> right atrium –> tricuspid valve –> right ventricle –> pulmonary arteries –> lungs –> pulmonary veins –> left atrium –> mitral valve –> left ventricle –> aortic valve –> aorta –> body…

An Introduction to Skeletal Muscles: Properties and Physiology

The muscular system allows us to move and do our daily tasks. It also provides heat, stability, and blood flow for our body. There are three main types of muscular tissue: cardiac muscle, which comprises the heart muscle, smooth muscle, which comprises the linings of organs, and skeletal muscle, which are the muscles that help our body move. This article will focus on the physiology of skeletal muscles.

Seven General Functions of the Respiratory System

What is the respiratory system? In general, the respiratory system is a biological system that contains organs and structures that assist in gas exchange. Gas exchange involves the movement of carbon dioxide and oxygen between our circulating blood and air. In this educational lesson, we explore seven general functions of our respiratory system.
