Review

The human body relies on various interconnected systems to maintain homeostasis and ensure survival. The respiratory system is responsible for oxygenating blood and expelling carbon dioxide, featuring structures such as the lungs, trachea, and alveoli.

Review

Have thicker walls than atria's

Nervous system

Detects when blood turns slightly more acidic because of rising CO2 levels (H+), after detection, it sends the order to exhale to make acidity normal again.

Skeletal system

Ribs that protect the lungs and heart

Muscular system (helps in the contraction and expansion of the thoracic cavity)

Intercostal muscles

Abdominal muscles

Diapragm

Circulatory System

Heart
Cardiac Cycle

Vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary valve → Pulmonary artery → Lungs (blood leaves the CO2 and gets oxygenated) → Pulmonary vein → Left atrium → Mitral/Bicuspid valve → Left ventricle → Aortic valve → Aorta → Body → Repeat
