Cell membrane protects animals cells from harmful chemicals.

Explanation:

The cell membrane is a tough covering composed of the phospholipids and proteins and forms a bilayer around the cells. This acts as a semi-permeable membrane and controls the transport of ions, organic molecules and solutes to and from the cell through selective permeability.

The hydrophilic and hydrophobic properties and the corresponding polarity of the cell membrane and ionization status of the chemicals prevent the entry of harmful substances into the cell. The cell membrane functions as a barrier system and prevents the flow.

Descending colon is found between the transverse and sigmoid colon on the left side of the abdominal cavity.

<h3>What are the components of large intestine?</h3>

The cecum, colon, rectum, and anus are the components of the large intestine. Mesenteries are tissue folds that hold the colon and rectum in the belly.

Caecum: The colon and ileum (the last part of the small intestine) are connected by a pouch-like channel called the cecum.

Colon: The longest part of the large intestine is the colon. There are 4 sections in the colon-

  • Ascending colon: The colon begins with the ascending colon. It is located on the abdomen's right side. It continues upward until it reaches the hepatic flexure, a bend in the colon.
  • Transverse colon: Following the ascending colon and hepatic flexure is the transverse colon. The upper portion of the abdomen is where it is located. The splenic flexure, a bend in the colon, marks its conclusion.
  • Descending colon: The transverse colon and splenic flexure are followed by the descending colon. The abdomen's left side is where it is located.
  • Sigmoid colon: The colon's final section, the sigmoid colon, joins to the rectum.

Rectum: The lower portion of the large intestine that joins the sigmoid colon is known as the rectum. Its length is roughly 15 cm (6 in). It takes waste from the colon and keeps it there until the anus allows it to leave the body.

Anus: The aperture at the bottom end of the rectum known as the anus is where feces exits the body.
