The digestive system is a major body system affected by blood vessels and heart problems. thus option C is correct.
<h3>What is the circulatory system?</h3>
To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.
Heart and blood vessels problem directly affect the circulatory system. Blood vessel disease (Vasculopathy) The blood arteries that transport oxygen and nutrients throughout your body and eliminate waste from your tissues are affected by vascular disease (also known as vasculopathy). Plaque, which is composed of fat and cholesterol, slows or obstructs blood flow in your arteries and veins, causing common vascular issues.

Epithelial tissue is composed of the innervated and avascular layer of cells which are tightly packed. It forms the outermost layer of the body and protects the internal layers and organs.
This tissue can be classified into different categories based on the shape of its cell, and the total number of the layers.
The epithelial tissue with only one layers is known as the simple epithelial tissue.
The epithelial cells that are thin, flat, and scaly are known as the squamous cells.
While the cubodial cells are round or square in shape.
Hence, the given blanks can be filled with classified, simple, squamous, and square.
That thing would need to rely on some source of food to live. Plants are living and they rely on sun and water. Humans rely on calories.
Answer: The means for transmission of disease-causing microorganism is provided by the direct or indirect contact.
Microorganisms can cause disease only once they are transferred to the body. The disease causing microorganisms are termed as pathogens which are transmitted by several ways such as from skin to skin, by nuclei droplets, through blood and body fluids or via air. In vector transmissions the disease is carried by the parasitic insects via animals, air borne transmission occurs when microorganisms move through air or the dust particles, droplet transmission occurs by coughing, sneezing or talking by the person who is infected while indirect transmission occurs by physical contact or by touching contaminated objects.
