SWALLOWING

  https://docs.google.com/presentation/d/1a_rfe2oiz8pYIUAjlp8wRC6MfG2txWsQ/edit?usp=sharing&ouid=102179593665048391458&rtpof=true&sd=true This work focuses on the process of swallowing. Swallowing involves three main stages: Oral Phase: Food is chewed and mixed with saliva to form a bolus. The tongue then pushes the bolus to the back of the mouth. Pharyngeal Phase: The swallowing reflex is triggered. The soft palate rises to block the nasal passage, and the epiglottis covers the larynx to prevent aspiration. The bolus is pushed into the esophagus. Esophageal Phase: The bolus moves down the esophagus via peristaltic contractions and passes through the lower esophageal sphincter into the stomach. The sphincter then closes to prevent backflow.

Mechanical digestion in the stomach  occurs via peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus, termed propulsion .  

NUTRITION

In the process of nutrition, organisms utilize nutrients. The main nutrients are carbohydrates, fat, protein, vitamins, and minerals.

MERISTEMATIC TISSUE

This tissue is found in the growing regions of plants such as the tips of roots, stems, and branches. The function of meristematic tissue is to make plants grow.

The food contains 3 macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins.

Animal tissues

ANIMAL TISSUE Animal tissue is  the types of tissue specific to animals, including humans . These tissues differ from those found in plants and other organisms. There are four basic types of animal tissue: epithelial tissue, connective tissue, muscular tissue, and tissue. https://docs.google.com/presentation/d/1G-Ow3ru Animal tissues ZMSJw5zjdf5tmw_s5RNCZiUOo/edit?usp=drivesdk&ouid=102179593665048391458&rtpof=true&sd=true
