Body Systems Analysis

Overview

The body obtain energy through cellular respiration, which requires oxygen to occur and produces CO₂ as a by-product. The circulatory system, also known as the cardiovascular system, transports oxygen and removes CO₂ in our body. This is achieved through a heart, wich acts like a pump, and various blood vessels, which are the pipes.
The circulatory system is deeply connected with the respiratory system, as some blood veins pass through the lungs to take oxygen and release CO₂.

The Heart

The heart is the core component of the circulatory system. it pumps blood through the body. This is done by contranting and expanding. The heart is geniously designed to have two cycles, one for oxygen-poor blood (blue) to go to the lungs, and another cycle for oxygen-rich blood (red) to go to the rest of the body.

Blood flow

The genious of nature is shown through the way blood flow through the heart. To absorb oxygen, blood vessels in the lungs are extremely thin. This means that part of the circulatory system have to be under low pressure to protect the vessels. However, the body is vast with thousands of KMs of vessels. Most of the system have to be under higher pressure for blood to reach everywhere.
Instead of two pumps, the heart is divided into two sections. one of those sections is for oxygen-poor/low-pressure blood that goes to the lungs, while the other half is for oxygen-rich blood that go to the rest of the body.

During Exercise

During excersize, muscles need more energy to move. The circulatory system work harder to cover for the extra oxygen needed from muscle cells. This is represented mainly by the heart beating faster to pump more blood through.
