Anatomy of the Intestines01:23

Anatomy of the Intestines

71.3K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

205
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Overview of Respiratory System01:23

Overview of Respiratory System

3.2K
The respiratory system is a complex biological apparatus that facilitates the exchange of gases, specifically oxygen and carbon dioxide, between our bodies and the environment. This system plays a vital role in the physiological process of respiration, an essential function for sustaining life.
What is the Respiratory System?
The respiratory system consists of a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary function of the respiratory system is to...

Surface Membrane Barriers01:18

Surface Membrane Barriers

1.0K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Respiratory Regulation of Acid-Base Balance01:18

Respiratory Regulation of Acid-Base Balance

266
Respiratory compensation is a vital physiological process that stabilizes blood plasma pH by regulating the partial pressure of carbon dioxide (PCO2), a key determinant of pH levels. Most carbon dioxide in the blood dissolves and converts into carbonic acid (H2CO3). It dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3⁻). There is also an inverse relationship between PCO2​​ and pH.
When carbon dioxide levels increase in the blood, more H+ and HCO3⁻ are...
