Blood Components and Circulation

Hemoglobin in red blood cells transports oxygen throughout the body.
Cardiac muscle tissue is responsible for the contractions of the heart.
The left side of the heart pumps oxygen-rich blood to all parts of the body.
Capillaries facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and tissues.
Arteries have thicker walls to support blood moving under high pressure.

Functions of Blood Components

Platelets play a crucial role in clotting to prevent bleeding and facilitate wound healing.

Respiratory System Structure and Function

The primary function of the bronchi is to conduct air to the lungs.
The trachea, supported by rings of cartilage, maintains open airways for unobstructed airflow.
Alveoli are responsible for gas exchange, allowing oxygen to enter the blood and carbon dioxide to be expelled.
The bronchi branch into smaller airways like tree limbs leading to the alveoli.

Nasal Cavity and Airway Protection

Mucus membranes in the nasal cavity produce mucus to trap foreign particles and humidify incoming air.
The respiratory epithelium contains tiny cilia that help trap and move foreign particles and pathogens out of the airways.

Lung Function and Airway Details

The primary function of the left lung is to facilitate oxygen exchange and gas exchange during breathing.
Bronchioles, the smallest airways, regulate air flow to the alveoli and play a role in airflow resistance.
Alveoli are located within the lungs, specifically at the ends of the bronchioles where gas exchange occurs.
