Human heart is made up of A. Nervous tissue B. Cardiac muscle C. Nonstriated muscle D. Connective tissue

Nervous tissue
Cardiac muscle
Nonstriated muscle
Connective tissue

The correct answer is B. Cardiac muscle.

Cardiac muscle is a type of striated muscle found in the heart. It is involuntary, meaning that it contracts without conscious control. Cardiac muscle cells are connected to each other by intercalated discs, which allow them to contract in a coordinated fashion. This is essential for the heart to beat effectively.

Nervous tissue is made up of neurons, which are cells that transmit nerve impulses. Nonstriated muscle is also known as smooth muscle, and it is found in the walls of hollow organs such as the intestines and bladder. Connective tissue is a type of tissue that supports and connects other tissues in the body.

Here is a table that summarizes the characteristics of each type of tissue:

| Tissue type | Characteristics |
|—|—|
| Nervous tissue | Made up of neurons, which are cells that transmit nerve impulses |
| Cardiac muscle | Striated muscle found in the heart; involuntary; contracts in a coordinated fashion |
| Nonstriated muscle | Also known as smooth muscle; found in the walls of hollow organs; involuntary |
| Connective tissue | Supports and connects other tissues in the body |
