Trachea (Windpipe):The trachea is a tube composed of cartilage rings that connect the larynx to the bronchi. It serves as a rigid conduit for air passage and is lined with cilia that aid in the removal of mucus and foreign particles. Bronchi:The trachea bifurcates into two bronchi, leading...
Respiration.When you breathe, the air enters the nasal cavities and comes in contact with the mucus membranes, which warms the air’s temperature to a more suited degree for your lungs. From the nasal cavity, the air moves down thetrachea, commonly known as the “windpipe,” and down to ...
The lungs are two spongy, air-filled organs that are positioned on each side of your chest (thorax) and the function of the lungs is very important. Your trachea (windpipe) transports breathed air to your lungs via tubular branches known as bronchi. The bronchi split further into increasingly...
The bronchi are the two large tubes that carry air from the windpipe (trachea) into the lungs and back out again. A crucial part of the respiratory system, the bronchi function primarily as passageways for air, bringing oxygen into the lungs and expelling carbon dioxide. The bronchi branch...
Nose and Mouth:openings that allow outside air to flow into the lungs. They are also the primary components of theolfactory system. Pharynx (throat):directs air from the nose and mouth to the larynx. Larynx (voice box):directs air to the windpipe and contains vocal cords for vocalization...
As we breathe in through the mouth and nose, air flows into our trachea (windpipe) and divides into tree-like right and left bronchi and into the lungs into smaller branching bronchioles. These end in alveoli which are the main site of oxygen and carbon dioxide gas exchange. The lungs are...
Each lung consists of several distinctlobes. The right lung (the larger of the two) has 3 lobes --- the superior, middle, and inferior lobes. The horizontal fissure separates the superior lobe from the middle lobe, while the right oblique fissure separates the middle and inferior lobes. The...
Swallowing takes place in the throat, partly as a reflex and partly under your control. The tongue and soft palate—the soft part of the roof of your mouth—push food into the throat, which closes off the windpipe. From here, the food travels to the esophagus or swallowing tube. Esophagus...
Bronchioles are air passages inside the lungs. They branch off like tree limbs from thebronchi—the two main air passages through which air flows from thetrachea(windpipe) after being inhaled through the nose or mouth. Bronchioles are vulnerable to conditions like asthma,bronchiolitis,cystic fibrosis...
The human respiratory system is comprised of special organs designed to take in oxygen for the air we breathe and expel carbon monoxide, keeping us alive. Let's take a closer look at these organs and explore respiratory physiology in more detail.
