Tejidos del cuerpo humano

• Exercise to test knowledge of tissues

Tissues

• Tissues consist of cells

Cytology vs. Histology

• Cytology is the branch of biology that studies cells
• Histology is the branch of biology that studies tissues

Tissue Definition

• A tissue is a group of cells that perform the same function

Epithelial Tissue Types

• The two types of epithelial tissue are lining epithelium and glandular epithelium

Skin Layers

• The three layers of skin are epidermis, dermis, and hypodermis

Gland Definition

• A gland is an organ or group of cells that produces and releases substances.

Gland Types

• The types of glandular tissue are endocrine and exocrine

Endocrine vs. Exocrine Glands

• Endocrine glands release hormones into the blood, while exocrine glands release substances to the exterior or into cavities

Connective Tissue Function

• The main function of connective tissue is to support, protect, and connect other tissues and organs

Alternative Name for Connective Tissue

• Connective tissue is also known as conjunctive tissue

Tissues Dependent on Connective Tissue

• Tissues that are dependent on connective tissue are bone tissue, cartilaginous tissue, adipose tissue, and blood

Most Extensive Tissue

• The most extensive tissue is connective tissue

Tendon Function

• The function of tendons is to connect muscles to bones, allowing movement

Adipose Tissue Function

• The function of adipose tissue is to store or reserve energy, protect organs, and regulate temperature

Adipose Cell Name

• The cells in adipose tissue are called adipocytes

Cartilaginous Tissue Function

• The main function of cartilaginous tissue is to provide structural support and flexibility

Cartilage Locations

• Cartilage is found in the ears, nose, bronchi, trachea, joints, and lining some bones

Cartilaginous Tissue Cell Names

• Cells of cartilaginous tissue are called chondroblasts or chondrocytes

Number of Bones in Human Body

• The human body has 206 bones

Types of Bones

• The three types of bones are long, short, and flat

Bone Tissue Function

• Bone tissue provides support to the body, protects it, and produces blood cells.

Types of Bone Tissue

• Bone tissue is classified into spongy bone tissue and fibrous or compact bone tissue.

Red Blood Cell Formation Location

• Red blood cells are formed in spongy bone tissue

Bone Tissue Cell Name

• The cells of bone tissue are called osteocytes

Chemical Substances Forming Bones

• Bones are formed by calcium phosphate, collagen, and calcium carbonate

Examples of Bone Types and Locations

• Flat bones: Cranium, scapula
• Long bones: humerus, femur
• Short bones: carpals (wrist), patella

Blood Tissue Function

• The function of blood tissue is to transport oxygen and nutrients to different organs, and to collect metabolic waste such as CO2

Blood Tissue Cells

• The cells of blood tissue are red blood cells or erythrocytes, white blood cells or leukocytes, and platelets or thrombocytes

Blood Tissue Matrix Name

• The matrix of blood tissue is called blood plasma

Blood Tissue Cell in Wound Healing

• Platelets in blood help to heal wounds by stopping hemorrhage

Blood Cell Responsible for Oxygen Transport

• Red blood cells carry oxygen throughout the body

Blood Cell Responsible for Eliminating Invasive Organisms

• White blood cells eliminate infectious organisms

Nervous System Function

• The function of the nervous system is to transmit electrochemical impulses that make reflexes and movement possible, and to respond to stimuli

Neuron Parts

• The parts of a neuron are the cell body, nucleus, dendrite, and axon

Types of Muscle Tissue

• The types of muscles tissue are striated, cardiac, and smooth

Number of Muscles in Human Body

• The human body has between 650 and 840 muscles, voluntary and involuntary

Examples of Muscles

• Examples of muscles: biceps, abdominal, uterus, liver, and intestine
